The image of the Emperor or Empress appeared on Indian currency, in government buildings, railway stations, courts, on statues etc.
Oaths of allegiance were made to the Emperor or Empress and the lawful successors by the governors-general, princes, governors, commissioners in India in events such as imperial durbars.
After the nominal Mughal emperor Bahadur Shah Zafar was deposed at the conclusion of the Indian Rebellion of 1857 (10 May 1857 – 1 November 1858), the government of the United Kingdom decided to transfer control of British India and the princely states from the mercantile East India Company (EIC) to the Crown, thus marking the beginning of the British Raj.
The EIC was officially dissolved on 1 June 1874, and the British prime minister, Benjamin Disraeli, decided to offer Queen Victoria the title "Empress of India" shortly afterwards.
By 1874, Major-General Sir Henry Ponsonby, the Queen's private secretary, had ordered English charters to be scrutinised for imperial titles, with Edgar and Stephen mentioned as sound precedents.
The Queen, possibly irritated by the sallies of the republicans, the tendency to democracy, and the realisation that her influence was manifestly on the decline, was urging the move.
